Which of the following would exert maximum osmotic pressure?

Options

A. Decimolar aluminium sulphate
B. Decimolar barium chloride
C. Decimolar sodium chloride
D. A solution obtained by mixing equal volumes of (B) and (C) and filtering

Explanation

To determine which of the given species would exert maximum osmotic pressure, we can follow these steps:

### Step 1: Understand the Formula for Osmotic Pressure
The osmotic pressure (π) is given by the formula:
\[ \pi = iCRT \]
where:
- \( \pi \) = osmotic pressure
- \( i \) = Van't Hoff factor (number of particles the solute dissociates into)
